6. An Experiment made with the four Feet Rod, 
and a Brafs Plate four Feet fquare. This was placed 
upon a Stand, fo that the Plate Rood perpendicular, 
the Stand being fet op the Cylindrick Glafs ^ then the 
Rod with its Stand and Glafs was fet fo as that one 
Point of it was about an Inch from the Centre of the 
Plate ; then the Tube being applied to the other End 
of the Rod, and after going to the Plate, on ftriking

a fmall hilling Noife,and'thePricking was felt as when 
the Experiments were made with the pointed Rods. 
7. A Pewter Plate being laid upon the Stand, which 
Had been fet upon a Glafs Cylinder, the Tube firft, 
and then the Finger applied, there appeared a Light 
upon the Plate, and the End of the Finger was pufh-

the Plate, there was a Snapping heard, but not fo loud 
as when the Iron Rods were ufe^. I then filled the 
Plate with Water, and applying the Tube and Fin- 
ger as before, there was the fame Light, pufhing of 
the Finger, and Snapping, as when the Experiment 
was made with the empty Plate. When the Experi-
